T all whom. it may concern:

Be it known that I, ARTHUR V. SMITH, a citizen of the United States, and resident of the borough of lllanhattan. city of New York, in the county of New York and State of New York have invented certain new and useful Improvements in Rype-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and more especially to the line spacing mcchai'iism of such machines.

The main object ofmy invention is to provide a simplified and improved construction of the character specified.

To the above and other ends the invention consists in the features of construction. combinations of devices and arrai'igements of parts hereinafter explained and particularly 2o pointed out in the claims.

In the accompanying drawings, Figure 1 is a fragmentary top plan view of a platen and its mounting, and showing my improved line spacing devices applied thereto. Fig. 2

is a side elevation of the parts shown in Fig. 1. with the platen finger wheel removed. Fig. 3 is a fragmentary front elevation of the platen and its line spacing mechanism. Fig. 4 is an enlarged perspectiw, view of the adjustable stop for the line spacing pawl and showing the support. for said stop.

Figs. 5 and (i are enlarged detail end elevations and sections respectivelyof the adjustable stop for the line spacing pawl and showing the mounting of the same. Fig. 7

is a fragmentary top plan view of the platen and its line. spacing mechanism, the parts being shown as they appear when tholinc spacing pawl has just engaged with the line spacing ratchet. wheel. Fig. 8 is a view corresponding with Fig: 7 and showing the line spacing pawl at the completion of the line spacing movement and cooperating with the line spacing stop. Fig. 9 is a view corrcswan ling to Fig. 8 but showing the. adjustable linc spacing stop sot. dill'ercntly. Fig. .10 is.a View corresponding with Fig.; 8 but providing bearings for a platen axle 6 which showing the adj'islal'ilc line spacing stop set (lillcrcnlly from the ways in which it. is set so in Figs. 8 and l).

In the. drawings. 1 represents the frame of the machine supporting roller hearings Q with which engage guide bars 3 secured on a carriage truck 4. A. platen carrier 5 is as mounted in said truck 41, said platencarrier supports a cylindrical rotary platen 7. Operatively connected with one end of said platen is a line spacing ratchet wheel 8 provided with peripheral teeth 9 and crown teeth 10. Arranged below the ratchet wheel and cooperative with the peripheral teeth 9 is a detent roller 11 journal ed in a spring arm 12 secured by a screw 13 to the platen carrier.

The side of the platen carrier 5 adjacent to the ratchet wheel -S terminates in an arm 14 which. extends forwardly beyond the platen and near its end is curved or offset inwardly. as clearly appears in Fig. 1. A forwardly extending line spacing lever 15 is bifurcated or forked at its inner end, the arms 10 and 17 of the bifurcated portion embracing the end of the arm 11 which end is enlarged and formed with a vertical hole which serves as a journal or hearing for a pivot screw 18. The screw 18 passes through an opening in the arm 17 down through the hole. in the arm 14 and at its lower end is provided with threads which engage a threaded opening in the arm 16 of the line spacing lover. The forward end of the line spacing lever 15 is provided with a finger portion it). The upper arm 17 of the lever 15 overhangs the. lower arm 16 and is cut away 'or bifurcated atv 2Q to provide upper and lower walls or arms 17 which receive.

bet ween them the. pivot. end of a line spacing pawl 21. A pivot screw 2 passesflotvn- 'ardly through openings in the upper wall 17 and in the pawl. ll, and its lower end which threaded is received in the threaded opening of thc.lower wall 17. The pawl Qt-projccts rearwardly from its pivot 29. and is provided near its rear end with a pin or lug 23 which depends from its under side. A. coiled detachable spring "24 lies beneath the pawl 21 and has its rear end secured to the .pin .23 and its fomvard end to a. pin or lug 25 extending upwardly from the arm 14.

ICC

The spring YZ-lserves norn'ially to maintain pawl stands some distance away from the crowuteeth 10 of the ratchet wheel 8 with a threaded opening which receives an ternally threaded bearing sleeve .llic

which teeth said pawl is adapted to cooper yoncl the sides of the other stop portions 29 is reduced indicated at 29 the duced portion receiving a polygonal hing piece 53, the faces of which are provided. with numerals to indicate the Corresponding stop faces at the other end of the '1 T when the numeral *1 is shown in'l i 1,,the stop i ate Whenthe lever 15 is actuated.

Above the platen axle 6 the side of the platen frame 5 is provided with an upwardly extending arm 5 which arm is formed with hearing opening in the sleeve :2] receives the shaft 29 of a rotary stop member, the inner end of said shaft being provided with a plurality of sloping stop faces or portions 30,31 and 32, which are at different distances from the pivotal axes of the shaft 29. 'l he sides of the portion 30 extends slightly beas indicated 2630 for a purpose presently to be described, The outer end of the shaft that ijljort only a single tooth space of the platen v be presented in the operative position whereas, when the numeral 2 is uppermost, the stop lace which ati'ords a two tooth space movement of the platen is presented in the operative position and so on. linger piece 33 is secured to the reduced ptnlion 29* of the shaft by any suitable means as a pin 34.

It will be noted from an examination of Fig. 6 that the sleeve 27 fits snugly he the inner face of the finger portion the oppositeface of the head formed by stop portions so that any longitudinal. mot ment of the sleeve will be transmitted to the stop member as a whole. A frat spring 35. is secured to the platen frame in any sn' able manner as by a screw 36, and. .d spring is provided at its free end with contact portion 35 which bears against any one of the flat sides of the stop carrier and niaintains said stop member or carrier in adjust ed position and is adapted to yield sulli c'iently to permit said stop member to be turned so that one stop face'or another said stop member may be brought into op; erative position.

The projections 30 01 the stop portion 30 are adapted toengage with the sides of the contact piecenB on the free end. of the spring 35, as shown in Fig. 5, so as to prevent a continuous turning of the stop member in either direction and so that some one of the stop portions 30, 31 or 32 will at all times be in position to cooperate with the line spacing pawl 21.

When the line space movement has been completed and the spring.24 is exerted to turn the lever and the pawl 21 about their-pivots backward to normal position. During the first part of the return movement the pawl is maintained in contact with the ratchet wheel by the spring. As soon as the pawl contacts with its back stop it swung away from the ratchet wheel and is turned about the pivot 18 along with the lever 15.

When it is desiredto turn the platen in line space direction through a distance rep- ;resented by two teeth of the ratchet wheel,

the finger piece '33 is turned until the face bearing the numeral 2 is uppermost, thereby bringing the stop face 31 into position to coi'perate with the line spacing pawl. The parts are so proportioned vand arranged that when the lever 15 has been pressed from the normal position represented by the dotted lines in Fig. 9 to the full line position in said figure (in which position. it will be noted, the pawl 21 hasxbeen brought into contact with the face 31 on the stop mem= her) the platen will have been turned sented by two teeth of the line spacing ratchet wheel. 7 The operations of the lover the pressure exerted on the line space lever becomes effective to move the carriage tolthe right, so that a line spacing operation of the lever 15 is released, the force of the restoring lever against the slight pressure of the spring 24 may be effected, when desired, without moving the carriage to the right. It will further be seenthat the pivot end of the line spacing pawl is contained within the line spacing lever so that said pawl is housed in said lever, while the journal or hearing of the lever is also contained within or housed in said lever, while the restoring spring 24 is beneath said pawl and for the most part out of sight of the operator. These features of construction conduce to the simple and attractive ap wrance of the mechanism.

Various changes may be made in the construction and arrangement of different parts within the scope of my invention.

"What I claim as new and desire to secure by Letters Patent, is:-

1. in a typewriting machine, the combination of a platen frame: a rotary platen j therein: a line spacing ratchetwheel opera- 'tively connected with said platen; alin'e spacing lever pivoted on said platen frame;

I a line spacing pawlon said lever; and a through a double line-space distance repre- 15, pawl 21 and spring 24 are similar to those hitherto describedin connection with Figs. 7 and 8.

When it is desired torotatc'thc platen in line spacing direction throngha triple space, represented by three teeth of the line spacing ratchet wheel, the finger piece 33 is turned until the face bearing the numeral Q 3 is uppermost, in which position, as will be seen'by reference to Fig. 10, the Stop face 32 has been brought into position to cooperate with the pawl 21 to limit the movement of the latter in line spacing direction. The parts are so proportioned that: in this relation the pawl 21 operates to turn the platen rearwardly through a distance represented by threeteeth of the ratchet: wheel 8.

It will be seen that by my invention I provide a line space mechanism which is simple and substantial in construction and appearance and certain in operation, and that the direction ,of movement of the line spacing lever, or the pull thereof, is in substantially the same direction as is the pull of the carriage when the latter is returned to begin a new line of writing, so that a single movement of the line spacing lever in one direction may be given to effect a line spacing movement of the platen and to reseen that a line spacing movement of the platen must first be effected and the pawl single spring connected directly to said pawl and operative both on said lever and on said pawl to restore them to normal position.
